You can get error message in process work ganeti iwth private ceph cluster, when ganeti must use special pool and special user name. I suppose you already know how add environment for rbd in code of python of ganeti, so as ganeti is very poor guy in this context.

Ganeti tries to parse shell output from command of ‘rbd shomapped’. Child style of coders of google. LOL. And of course is using wrong parameter.

The current best way to do this is to run ‘systemctl edit service’, which will create an override file for you or let you edit an existing one.

In normal installations this will create a directory /etc/systemd/system/service.service.d, and inside that directory create a file whose name ends in .conf (typically, override.conf), and in this file you can add to or override any part of the unit shipped by the distribution.

For instance:

123

# systemctl edit ganeti-noded>>>invimenv you can see >>>"/etc/systemd/system/ganeti-noded.service.d/.#override.conf6940d208e8dfaced" 0L, 0C
